Scope

This Standard specifies the silicon metal’s requirements, test methods, inspection rules,
marking, packaging, transportation, storage of silicon metal, and purchase order or
contract contents.
This Standard applies to the silicon metal that is produced from the smelting of
carbonaceous reductant and silica in the submerged arc furnace. It is mainly used for
preparation of alloy, extraction of polycrystalline silicon, and manufacturing of organic
silicon etc.
